The root diameter (30) at the first axial end is substantially equal to the diamet~~ the elongated shaft (22) itself. The pin (20) also includes a drill end (26) extending axially from the second axial end ~~~~ threaded portion (24) such that the drill end (26) is connected to the elongated shaft (22) by the threaded portion (24). Also ~~~          closed is a preferred method of forming the threaded portion (24) on the pin (20) including the steps of: rotating the pin (20) ~~ about its longitudinal axis (44); moving a cutting surface (40) at a predetermined speed across an axial portion of the rotating pin (20) to thereby cut threads (28) in the axial portion; and linearly increasing the distance between the cutting surface (40) and the longitudinal axis (44) of the pin (20) as the cutting surface (40) is moved across the axial portion of the pin (20).

Title: Shortbread having a perceptible cooling sensation
Inventor: SULLIVAN JOANNE
IPC: A21D13/08
Filed: 1993-12-03
Abstract: Shortbread having a refreshing cooling sensation upon eating contain confectioners' sugar and fats bearing long, saturated C16 to C22 fatty acid residues and a mixture of short C2 to C4 acid residues, a portion of which are propionic acid residues. One preferred embodiment contains fats bearing acetic and propionic acid residues and residues of fatty acids derived from fully hydrogenated oils containing at least about 75 % stearic acid such as hydrogenated soybean oil or hydrogenated canola. Another preferred embodiment contains fats bearing a mixture of acetic, propionic and butyric and the same complement of long acids. These fats are low in calories, low in myristic and palmitic acid and trans unsaturated acid residues, and low in cholesterol. The cooling sensation imparted to the shortbread of this invention is achieved without adding other cooling-imparting ingredients such as dextrose, mint oils, or polyols, and can mask the burning sensation of artificial sweeteners and other ingredients.

Patent CA-2131806-A1 (CA)
Title: Data compression process during storage and/or transmission of digital audio signals for studio applications with perceptive coding and variable length code
Inventor: BRANDENBURG KARL-HEINZ
IPC: H04H20/95
Filed: 1993-02-25
Abstract: DATA COMPRESSION PROCESS DURING STORAGE AND/OR TRANSMISSION OF DIGITAL AUDIO SIGNALS  FOR STUDIO APPLICATIONS WITH PERCEPTIVE      CODING AND VARIABLE LENGTH CODE     ABSTRACT            A description is given of a process for data reduction in the storage and/or transmission of digital audio signals.  Known processes such as e.g. ASPEC permits the transmission of high quality music with a data stream containing less than 10% of the information of the data stream used in the CD.  However, known reduction processes do not meet the demands of professional studio technology, because the reprocessing of the audio signals used there leads to audible interference.            The process according to the invention is not sensitive to reprocessing operations, such as tandem coding, mixing or fading. This insensitivity is achieved in that the imaging of the audio signal from the time range into the frequency range takes place with the aid of a filter bank having perfect reconstruction, in that the psychoacoustic masking effect is used to a much smaller extent and in that as the variable word length code use is made of a cascaded, multidimensional Huffman code.            The process permits a transmission of audio signals for studio technology with a data rate of 192 kbit/sec/channel.

Title: Antenna Apparatus
Inventor: KONISHI YOSHIHIKO
IPC: H01Q21/29
Filed: 1994-11-15
Abstract: Herein is revealed a helical antenna apparatus wherein the direction of beam radiation hardly changes even if the frequency in use changes.  Two helical antennas which are wound with two conductive wires spirally, respectively, at equal intervals with a specified pitch .alpha. in the form of a cylinder are disposed along the length of the helical antennas so that the axes thereof substantially coincide with each other.  By determining the lengths of the feeders of the respective helical antennas appropriately in order to set the phase of supplied power, it is possible to form the beam of signals radiated into space in the shape of conical beam having a directivity oriented obliquely upward.  Additionally, it is possible to obtain the conical beam in which the direction of beam radiation does not change even if the frequency in use is changed.

Title: Hot gas filtration system fail-safe and thermal regeneration device
Inventor: BACHOVCHIN DENNIS MICHAEL
IPC: B01D39/20
Filed: 1995-04-24
Abstract: A fail-safe back-up filter system for filtering particles from a flow of hot gas in a coal gasifier or the like in the event of a failure of the primary filter system. In the event of a break in one of the primary filter elements of the filtration system, the back-up filters, having a higher porosity  than  the  primary  filters,  begin  to  collect particulate matter such that the particulates become embedded in the back-up filter.  After a period of time, the back-up filters become clogged and prevent the flow of particle laden gas through the back-up filter and the corresponding primary filter  such  that  the  flow  of  gas  is  diverted  into communication with the remaining, properly functioning primary filters.    The  back-up  filters  also  provide  a  thermal regenerator device for heating the flow of cleaning gas before it contacts the primary filter elements during back-flush cleaning in order to avoid the effects of extreme temperature fluctuations on the primary filters.

Filed: 1995-07-28
Abstract: In  a  burner  which  consists  of  a  swirl generator  (100)  on the oncoming-flow side,  the  flow (40)  formed herein is passed smoothly into a mixing section  (220).  This  is  done  with  the  aid  of  a transition geometry which is present at the start of the  mixing  tube  (220)  and  consists  of  transition passages (201) which cover sectors of the end face of the mixing section (220), in accordance with the number of sectional bodies of the swirl generator (100), and run helically in the direction of flow. On the outflow side  of  these  transition  passages  (201),  prefilming bores (21) pass through the mixing section (220), which prefilming bores (21) initiate an increase in the flow velocity  along  the  tube  wall.  Adjoining  the mixing section (220) is a combustion chamber (30) in which a backflow zone (50) forms in the region of the jump in cross-section   between   mixing   section   (220)   and combustion chamber (30).

L'agent nucléophile peut être un liquide ou un gaz. Il peut s'agir de n'importe quel agent organique ou inorganique ayant un groupe capable d'effectuer un déplacement nucléophile de l'halogène, par exemple du chlore, de la surface du charbon. L'halogénation s'effectue en plusieurs heures, par exemple 24 heures.

Title: Mammalian phospholipase a2 nucleotide sequences, low molecular weight amino acid sequences encoded thereby, antisense sequences and nucleotide sequences having internal ribosome binding sites
Inventor: TISCHFIELD JAY A
IPC: C12N9/16
Filed: 1994-07-15
Abstract: Novel mammalian phospholipase (PLA2) nucleotide sequences and low molecular weight (about 14 KD) amino acid sequences encoded thereby are disclosed. More particularly, a cloned human HPLA2 cDNA  expressing HPLA2 -10 and its cloned rat RPLA2 cDNA counterpart, expressing RPLA2 -10, which are characterized as PLA2 Type IV, are disclosed. A second type of PLA2 cDNA, characterized as PLA2 Type III and exemplified by a rat PLA2 cDNA encoding RPLA2 -8 and a partial human PLA2 nucleotide sequence encoding HPLA2 -8, is disclosed. Expression of the cDNAs encode the two new types of PLA2 enzymes which have phospholipase activity. The novel PLA2s do not include disulfide bridges between cysteine amino acids 11 and 77 or elapid loops. However, the novel PLA2s may include amino acid COOH-terminal extensions which can vary in length. Seventeen of the eighteen absolutely conserved amino acids in all active 14 KD PLA2s are believed to be conserved in RPLA2 -8 and HPLA2 -8, whereas all eighteen are believed to be conserved in RPLA2 -10 and HPLA2 -10. Because me encoded sequences of RPLA2 -8 and HPLA2 -8 include only 16 cysteine amino acids, they have been designated as Type III. RPLA2 -10 and HPLA2 -10 are designated as Type IV since their encoded sequences include only 12 cysteine amino acids.
